*1. Please set up a filter constant to be R_VSS × C_VSS ≥ 51 µF • Ω and to be
R_VC1 × C_VC1 = R_VC2 × C_VC2 = R_VSS × C_VSS.
Caution 1. The above constants may be changed without notice.
2. It has not been confirmed whether the operation is normal or not in circuits other than the above
example of connection. In addition, the example of connection shown above and the constant do not
guarantee proper operation. Perform through evaluation using the actual application to set the
constant.
